Front camera not working after my iPhone dropped

I dropped my phone and it was just a little tumble and then later my phone was kinda glitchy and the front camera was not working and just defaulted to the back camera. Back camera is perfectly fine and my phone seems to be working fine too but my front camera isn’t working still. I’ve tried rstarting my phone but it seems like a hardware issue. There’s no crack in front of the camera so is this a major issue or can it be fixed without replacing the entire camera?
